The Corsair H150i Pro RGB

A single look at the H150i Pro RGB reveals how massive the cooler is. The radiator is so large that the hoses are not long enough for the block to reach its other end. The overall design is based on the common AIO cooler configuration of a single radiator, two hoses, and a single block that combines the copper CPU contact plate with a mini liquid pump. Such designs are usually using stiff corrugated tubing to prevent kinking but not this one, as Corsair went with thick-walled FEP (Fluorinated Ethylene Propylene) tubing with nylon sleeve braiding, which is more flexible and aesthetically superior.

Corsair designed the H150i Pro RGB to hold three consecutive 120 mm fans but the radiator itself is 400 mm long, requiring a case designed not only to hold three 120 mm fan in the row but also with enough space to fit a liquid cooling radiator. The massive radiator is a classic dual pass cross-flow design with tiny fins soldered on the thin oblong tubes. Despite its massive length, the radiator of the H150i Pro RGB is not actually very thick. It is just 27 mm thick, meaning that a total clearance of at least 55 mm is required using the stock 120 mm fans and taking into account the 3 mm screw heads. It is obvious that the designer of the H150i Pro RGB intended it to be usable with low speed fans, so the airflow resistance of the radiator had to be kept low.

The main block assembly of the H150i Pro RGB is jestingly small when compared to the massive size of its radiator. It is a very small assembly by any comparison, considerably shorter than the vast majority of AIO blocks that we have seen to this date. Most of the assembly is made out of plastic, with an octagonal body and a circular base. A silver frame surrounds the piano-black top with the company's logo. The rest of the plastic body is black, with chromed metallic parts. The block is powered via a SATA connector and has a 3-pin motherboard connector that serves only as a tachometer for speed/health monitoring. A flat cable that ends to three fan connectors also exits the block, for the power, monitoring, and control of the three radiator fans.

The copper contact plate is attached to the circular base of the block with eight screws. Although it is not machined to a perfect mirror finish, it is very smooth and perfectly flat, which is what matters for good thermal performance. Thermal material is applied to it and it comes with the Intel CPU mounting retention bracket from the factory. A retention bracket for AMD CPUs is included in the bundle. There was no bracket for AMD's Ryzen Threadripper processors inside the box of our sample but Corsair now mentions that the H150i Pro RGB does support AMD's Ryzen Threadripper processors, plus an extra TR4 mounting bracket part appeared in their website.

Corsair installed RGB lighting into the block. Once the H150i Pro RGB is powered, the company's logo and a ring surrounding the block will illuminate. The lighting colour and effects are programmable via Corsair's iCUE software if the USB cable is connected to one of the motherboard's internal USB 2.0 headers.

  

The new iCUE software is very flexible and allows for the interconnection of any compatible device, inside and outside the case. It is also possible to program the lighting colors to have a practical meaning, such as programming variable lighting colors for different CPU (or other) temperature readings. For example, you can set your Corsair K95 Platinum's keyboard lighting to blink red if the processor's temperature surpasses a certain point while, and even have the computer shut down if the temperature is sustained above a threshold for X seconds.

    looking at this review I see the nepton 280l still performs well enough. I replaced the fans on mine with corsair ml ones I at least know that did not have any negative impact on thermals in my case. Reply

    I would love too see a review of the Alphacool Eisbaer 420mm. Reply

    I wonder if/when Corsair will star producing motherboards or graphics cards, two OEM products they dont appear to manufacture.... given their (to my untrained eye) high production quality their end product would be good kit... (and yea I figure motherboards and graphics cards are the most complex components to create after the CPU/GPU...) and would give them full component integration :) Reply

    as much as i love corsair products but for the love of God if youre willing to spend $170 then why not get EKs aluminum kit or save up for a copper liquid cooling system. 170 seems such a waste for an aio. these should be 60/70 at most $100 for the more sophisticated ones Reply

    I don't think you've kept up with inflation. $60–70 isn't realistic at all. Reply

    1: An AIO is super simple, plug and play.
    2: You cannot build a custom loop for anywhere close to $170.
    3: Custom loops require maintenance. An AIO you install it, and then let it do its thing for the next several years.

    Custom loops don't need a lot of maintenance.
    I purchased a diy asetek water chill about 20 years ago. I have replaced the fans and the water lock and 2 years ago the pump died. I top up the water roughly every 2nd year and have change the water 4-5 times during the systems impressive lifetime.
    Definitely the best Pc investment I ever made!

    My new build has an 8086K cooled by a Noctua NH-D15. All 5 case fans are Noctua. 8086K is OC'd to 5.0 MHz - all cores - at 1.280 Vcore. Idles at 33c. Prime95 stable for 1 hour - never over 85c. Who needs an AIO? Reply

    My 8700K overclocked to 5GHz at 1.3v does 28 to 30 Degrees in Idle (Living in UK) and does not exceed 80 degrees in Prime95... I am using the Corsair H150i Pro...Why do people use AIO's? Many reasons and for me having tried the Noctua in the past was how difficult it was to get at things when making changes and having something that heavy hanging of the CPU just wasn't for me. The H150i Pro is also super quiet and does a stellar job of cooling a overclocked CPU with minimum fuss. Reply

    And my lowest temp at idle today is 25 degrees!!!! Reply
